So, this is the situation. My gf has a macbook (white, 13 inch), running OSX 10.6. I have a macbook pro (13 inch, running mavericks). When she is connected to the wifi network, all is fine. But, as soon as I turn on my macbook and connect, her connection drops and she has to use the second channel. Anybody knows what is going on here? Everything else stays connected (2 cellphones, tablet). Just her macbook drops as soon as I connect. Thanks in advance!
